UNITED STATES PATENT OF IC JUSTUS P. LUTHER, or BERLIN, wIsooNsIN.

COT.

SPECIFICATION forming part of Letters Patent No. 420,813, dated February4, 1890.

Application filed May 21, 1889\ Serial No. 311,506| (N0 model.)

To all whom it may concern: 7

Be it known that I, J Usrus P. LUTHER, a citizen of the United States,residing at Berlin, in the county of Green Lake and State of WVisconsin,have invented certain new and usefullmprovements in Folding Cot-s, ofwhich the following is a specification, reference beinghad therein tothe accompanying drawings, in which Figure 1 represents a perspectiveview of my improved cot, a portion of one. end of the canvas beingbroken away; Fig. 2, an end elevation of the same; Fig. 3, a similarview showing the cot partly folded; Fig. 4, a detail sectional viewshowing method of clamping the canvas to the side rails; Fig. 5, a sideelevation of the cot, a portion of the side rails being broken away; andFig. 6, a detail perspective view of portions of two supportinglegs,showing the bar for preventing lateral or endwise vibration of the cot.

The object of the invention is, essentially, to produce an extremelysimple cot which shall possess the desirable qualities of durability,strength, and lightness in an eminent degree; and it consists in certainnovel features of construction, which will be fully hereinafterspecified, and particularly pointed out in the claim appended.

In the accompanying drawings, A designates the legs of the cot,preferably eight in number and arranged in pairs, the legs of each pairbeing crossed and pivoted together, as shown. The lower ends of the legsare secured and braced and held in alignment by the horizontalconnecting-rods B. The upper ends of the legs are provided with tenonsa, which are adapted to fit snugly into suitable sockets in the siderails 0, these rails being thereby securely attached to the upper endsof the legs. Nails or screws a may be employed to secure the tenons intheir sockets, if desired, or the tenons may be glued therein.

Olamped to the upper inclined faces of the rails O, by means of screws1), are the clamping-strips D, the said screws 1) being passed upthrough the rails and screwed into the strips D, as shown. Olampedbetween the strips D and the rails are the longitudinal edges of thecanvas E, the edges of the canvas being passed over the tops of the saidstrips and inserted between the same and the lower rails from theoutside, the clamping strips being thereby covered over and hidden. Theupper faces of the clamping-strips are rounded to prevent undue Wear orcutting of the canvas. The canvas is thus clamped removablybutsecurelyin place Without tacks or nails.

To brace the cot against endwise vibration, I secure to the outer sidesof the legs, up close to the side rails, bars F, which extendapproximately the full length of the cot, and are recessed, as shown inFig. 6, at the proper points to receive the legs.

To stretch the canvas and prevent sagging of the same at the head of thecot, I employ the toggle-levers c c, the adjacent ends of the leversbeing pivoted together and their outer ends to blocks cl, secured in thecorners formed by the side rails D, the bars F, and the legs. One of thelevers is provided with an extension 0, which, when the canvas isstretched, extends over and abuts against the lower inclined face of theopposite side rail, and thereby locks the levers against accidentaldisplacement, the end of the said extension being beveled to fit againstthe inclined face of the rail.

To fold the cot it is simply necessary to unlock the toggle by pressingdown upon its joint, and then drawing the side rails toward each other,as shown in Fig. 3.

It is evident that I may employ this method of clamping the canvas inthe construction of camp stools, canvas-topped tables, and otherfurniture.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-- The combination of the crossed legs A,provided with tenons on their upper ends, the side rails provided withmortises for the re ception of these tenons, the side strips F, se-
